SPECIFICATION forming part of Letters". Patent No. 235,432, datedDecember 14, 1880.

Applicationled June 2, 1880. (No model.)

To all whom it may concern.-

Be it known that I, HENRY HASSENPELUG,

` mechanical movement. Fig. 2 is a partial side view of the same,showing'the parts in a different position. Fig. 3 is a cross-section ofsame.

This invention relates to a new mechanical movement useful forvpropelling vehicles, driving machinery, and the like 5 and it consistsof a new combination-of parts for converting the rotary motion of adrivingfshaft into oscillating motion of an elbow-lever, whichoscillating motion is again converted into rotary motion of the drivenshaft, the entire mechanism being .readily reversible.

In the drawings, A is the driving-shaft, and B the shaft to be driven,both said shafts being hung in a suitable framework, C.

The shaft A carries a suitable crank-handle, b, for turning it, saidcrank-handle being preferably slotted, to be adjustable as to length andpower.l The shaft A carries also' a toothed wheel, a, which is eccentricon the shaft, as shown, andwhich is between two toothed racks, c and d,formed above and below it on an elbowlever, D, that is hung to the frameO at c.

`The distance between the racks @and d equals the double length of thelarger radius of the eccentric-pinion a and exceeds the diameter of saidpinion, so that upon being revolved the pinion will rst gear into therack c and then into the rack'd, and so on, and never into both racks atonce. By thus alternately gearing into theracks c d the pinion willcarry the one rack to the right and the other to the left, and therebyoscillate the lever D.

An arm, f, of the lever'l) connects by a rod, g, with a crank, h, of theshaft B, by which connection the oscillating motion of the lever D isconverted into rotary motion of the shaft B. The motion of the shaft Bwill be reversed without reversing the motion of the shaft A, accordingas the crank h stands to the right or left of the shaft B when theoperation of turning the shaft A commences. Thus, in the position shownin 1Eig. l, if the shaft Ais turned in the direction of the arrow 1, thelever D will first be moved in the direction of the arrow 2 and theshaft B turned in the direction of arrow 3,V the rod g being firstraised, and in this motion the shaft B will continue until arrested; butif at the commencement of operation the crank h and rod g were as indotted lines in Fig. 1, the motion of shaft B would be reversed withoutreversing that of shaft A.

Great power and certainty of action are obtained by this mechanism.

I claim- 1. The combination of the shaftAand eccentric-pinion a with thepivoted lever D, having racks c and d, the distance between which eX-ceeds the diameter of the eccentric-pinion, substantially as hereinshown and described.

2. The combination of the shaft A, eccentricpinion a, lever d, and itsracks c and d with the rod g and crank-shaft B, substantially as hereinshown and described.
